[Seaside] WeakArray problems (I think)

[Dmitry Dorofeev]

Hi,

I expirienced similar problems with CPU eating at 100% (UNIX top command output)
Image did not respond to socket requests at all. I sow it on FreeBSD quite
frequently and on Linux time to time. I decided that it might happen becouse
image takes all memory I left it to have with -memory switch to squeak command. 

To stop it I run a daily Seaside clean up (I think the same as per link 'Clear caches'
on /seaside/config page). Hope that helps me, but not sure as it is only a week with this feature.

I run squeak as follows:
squeak -nodisplay -nosound -notimer -memory 512m esol.image

without memory limit it is not stable at all (seems a problem above 1Gb)

3.7-7 #1 Sat Mar 19 13:12:20 PST 2005 gcc 3.3.5
Squeak3.7 of '4 September 2004' [latest update: #5989]
