Re: [Zope-dev] Memory Error

[Andy McKay]

There we go, occurred again.

Its definitely the manipulating of catalog results, all the crashes are 
happening on zcatalog searches. There is over 530 Megs of Memory free at 
the time.

But like I say its never occuring my other boxes so time to whip out 
some unit tests and the like ;)

Re: [Zope-dev] Memory Error

Thanks for the responses everyone.

This message occured more frequently when I was showing the 
getNewOrRandom slot which does a few catalog searches and mucks them 
around. I've turned off that slot and setup a nightly restart cron.

I'm waiting for it to happen again (it hasn't yet), but it looks like 
the BTrees and Catalog results could be a place to start.

Its got a gig of ram and about 500 mb is free most of the time 
apparently, but next time it happens I'll see if I can get more info.

Just have to hurry up and wait now ;) Or wait for runyaga to visit it, 
he seems to have this curse with it.

In my experience, (at least on FreeBSD) it would simply fall over when it ran 
out of stack space, I don't remember ever seeing MemoryError. But I may not 
have been paying close enough attention ;^)

Looks like its running out of memory when a BTree subobject is being loaded. 
Do you have any idea how much memory the process was using when you got the 
error?

Just for the records, we were getting some MemoryError's on NZO, which
were track down to some weird repr() handling on ZEO/ZODB code. There
were also some fixes on memory leaks (an exception on a tal:repeat
would leak some objects, plus there was one small leak on plone's
portal_form) but none seem to be entirely related to your
problem. However it could be a side effect of a memory leak. I
would recommend getting ZODB from the new ZODB-3_2-branch, and plone
from the Plone-1_0 branch. And if youre not afraid of running from
CVS, get Zope from the 2_6-branch ;)

"MemoryError" would mean you have run out of virtual memory.

This may or may not be a Zope problem.
