OWB : vanishing memory?

I use OWB daily and am quite pleased with it, but...
...it consumes all my memory! I'll explain.
If left unused, the memory is relatively stable, but when in use, memory slowly vanishes until it locks up the machine.
Opening a second window makes it worse, but it happens with just one window, too.

Is there a (known) memory leak?
Are some temporary buffers not being cleared?

If I quit OWB, memory is usually returned, but the machine is slow (needing a reboot to be usable).

I'm using AOS4.0-Final,500MB RAM, Radeon 7000 and OWB3.29 (though it happened with other versions, too).
I'm thinking about buying AOS4.1 soon and would like to hear from users of that OS,too, if possible.

@BrandonLee

I've surmised it's a cache, in RAM, and if it tends to slow down the machine after quitting the browser, I haven't noticed. But certainly when the system starts swapping things (which happens sooner than later with 512 MB), that's clear as day.

Disabling this cache would probably ruin browsing on the same site, because the processing of complex sites would be for consecutive pages as slow as it currently is for the first page.

@Thematic

Understood.
But is it normal for said cache to use up the memory incrementally, so to speak, like that?
So far, 512MB have been fine, I rarely go out of memory (but having said that, OWB is probably the "biggest" application i use)

It's just that it's annoying to reboot every hour or so of Internet usage... ;(

@BrandonLee

It happens here at least.

Do you use many browser tabs? I manage with less than five normally, maybe that is why I don't see a large slowdown with all the restarts (I tend to restart when free RAM goes below 100 MB).

@Thematic

He uses OS4.0 so he doesn't have the memory cache and no swapping. The slowdown is due to heavy fragmentation in that old memory management (or lack of) in OS4.0.

@BrandonLee

I have OS4.1 and I have also noticed that OWB gradually eats up all memory. OS4.1 doesn't slow down though because of it. When the memory runs out it will start swapping. If I keep surfing it will eventually become so slow due to swapping that the computer becomes unusable. I usually quit long before that

I don't use tabs. My first attempts all resulted in crashes, so I decided to switch them off.

@Deniil715

Is there no way around this? Either by the user or by the programmer?

It's not very serious, but sometimes I lose downloads midway or actual stuff I'm "working" on because the computer locks up...

@BrandonLee
It is some kind of memory leak. Some website cause the browser to randomly leak memory like hell. Wunderground.com is one of those sites that does this to my system.

Sadly i guess no use in filing bug report considering it has apparently been discontinued .
I guess our only hope is timberwolf which i bet will never run good on my 533mhz sam system.

If it was a leak, you wouldn't reclaim the memory when quitting the program.

So what do you call it when ONE single website uses up all ram within seconds-minutes? If i dont quit it soon after it goes below 0MB free then system will eventually lock up completely.

I haven't encountered this problem as severely as you described. Typically no allocations are made when the browser is left alone, with opened pages.

Yes quite lame for os4 users. I cant believe the developer who received bounty money just decides to stop working on it s leaving the os4 community in the learch. And with the announcement of using FF 4 sources it will really be a while for Timberwolf (though when it arrives should be promising) to arrive. So you are probably stuck with the suckage for now.

Point everyone to this mystery OWB bounty you speak of, as it doesnt exist.

Yes considering his comment:

So, not included in OS4.0-Final.

It only happens on a few rare pages. Most of the time OWB works just fine, but parts of sites like wunderground.com can sometimes trigger this instantly. I literally can have 250meg free ram and then see it reach 0meg within a minute or so and then hear the system swap like heck until it locks up completely.

It is otherwise rock stable.

I'd say its a leak. Find it hard to believe it would cache over 150MB after quitting OWB in the cases it had started swapping. I then have less than 100MB free but over 200MB when I started. Starting it again should make it use the caches so no more memory should be reported being in use. Still it reaches the point of swapping way sooner. It leaks.

As Tomas says, it doesn't happen all the time, some sites make it eat memory.

@Derfs

search this site for the thread.... the dev took $$ for OWB and now halts development without full features... You would think he would at least bug fix the current version. fab does owb port for morph for FREE and its WAAAY ahead. This is one of the things holding back my os4 purchase atm no good web browser

@Deniil715

OS4 final was July 2007.
Entilzha's post in 2006 refers to it not being in update 4.
I concluded from that that is was in final, which was a year after his post that I just quoted. No?

No memory leak here with OWB. I guess must be a problem with your system, or that you are using an old version of OS4.

Please get your facts right. Joerg asked NOTHING for OWB, what people donated was for work he had already done (which was A LOT).

OWB *is* bug fixed, works really nicely on tons of web sites. Of course nothing is perfect, but I don't notice any problems.

OS4 *does* have a good web browser. It is called OWB. Lacks some features, but it does the main job of a web browser well - which is to browser web pages!
