[Vm-dev] unix SqueakSource socket 'too many open files' problem

[tim Rowledge]

I've been running a squeaksource system on a 64bit linux server for a year or so and just started having odd problems.

Talking with Chris about it, and looking into the assorted logs, lead to the theory that sometihng (unknown and I can't see how possible) caused the image to save and quit at some point when the expected behaviour is to *not* ever save. That lead to some complaints about Magma related details that don't matter here.

I had much fun (the usual linux user names/permissions stuff) but eventually got a new copy of the squeaksource image running. Yay!

Except after an indeterminate time (several hours, not a whole day) the webpage part of the sytem became unaccessible even though it had not actually crashed out. The log contained a bunch of lines like this -

... which are errors from the VM socket handlers.

I've not seen this happening before that I recall. Any ideas? Stuff to check? Solutions?
