[Zope] OS Error 24: Too many files open

[Astheimer, David (GXS)]

Folks,

Config: Zope 2.3.2 / Solaris 2.6

After 23 days of adding and removing files, we've bumped into a file
descriptor table
problem on our Solaris 2.6 platform. The situation was reported in a
standard Zope
error web response with the following contents:

Error Type: OSError
Error Value: [Errno 24] Too many open files: '/var/tmp/@12939.7266'

Unfortunately, I was unable to "lsof" the crippled Zope instance. However, I
have
looked at the restarted instance and found twelve long-standing open files
in the
/var directory.

Since file descriptors are a scarce resource in Solaris 2.6, I've jumped the
ulimit
value up to 256 and Zope is off and running again. Are long-standing
temporary
files a typical Zope signature? Did I miss a discussion of this topic?

Regards,
Dave
