Memory problem?

Hi all,

I'm having some (I guess) memory problems in Seaside, after a while using a running website, changing some pieces of code, refreshing, modifying CSS, etc. my squeak image starts running really slow, and the whole system gets terribly sluggish, so it is that I have to restart X11.

I know this is way too little information for a diagnose, but since I don't know which information should I give, I attach the memory usage at the exact time of the image beginning to get sluggish and the squeak log, which I was unable to understand. If you need it, I could also attach the website's .st file.

Oh BTW, I'm using Seaside 2.8 running on a Squeak 3.9-8 vm with Debian Lenny.

Thanks a lot in advance!

Bernat.

Re: Memory problem?

Can you open a process browser in squeak when it happens.

I have had simillar behaviour when there is an infinite loop somewhere
in the code.

Re: Memory problem?

Hi, thanks for your answer, I can't do did what you pointed to me because when the image hangs I can't do absolutely anything, but I found out there's a lot of TcpListener processes running even before the problem occurs:

Semaphore>>waitTimeoutMSecs:
Socket>>waitForConnectionFor:ifTimedOut:
Socket>>waitForAcceptFor:ifTimedOut:
[] in TcpListener>>pvtListenLoop: {[socket := listener     waitForAcceptFor: self acceptTimeout     ifTimedOut:...]}
BlockContext>>ifCurtailed:
[] in TcpListener>>pvtListenLoop: {[[socket := listener     waitForAcceptFor: self acceptTimeout     ifTimedOut...]}
Process class>>terminationOkDuring:
[] in TcpListener>>pvtListenLoop: {[Process   terminationOkDuring: [[socket := listener       waitForAcceptFor:...]}
BlockContext>>whileTrue:
TcpListener>>pvtListenLoop:
[] in TcpListener>>listenWhile: {[self pvtListenLoop: aBlock]}
BlockContext>>ensure:
TcpListener>>listenWhile:
[] in HttpService(TcpService)>>runWhile: {[(TcpListener on: self portNumber handler: self)   listenWhile: aBlock]}
BlockContext>>ensure:
HttpService(TcpService)>>runWhile:
[] in HttpService(ApplicationService)>>start {[self   runWhile: [stopSignal isNil     and: [process == Processor activePro...]}
BlockContext>>ensure:
[] in HttpService(ApplicationService)>>start {[[self   runWhile: [stopSignal isNil     and: [process == Processor activePr...]}
BlockContext>>on:do:

Anyways, I narrowed the problem a little bit, I just fanks!ound out it only happens when I edit the CSS from within the website, so it's not such a serious issue anymore, but I'd still like to know what did I do wrong...

Any ideas?

Thanks!

+1. It sounds like an infinite loop.
You can try showing process browser and debug seaside related proceces. Maybe
you can confirm something suspicius

Re: Memory problem?

Thanks all, I got it solved!

It really was something stupid I didn't remember to comment out, which resulted in an endless self-calling of self unregister... duh

Thanks again!
