[Asterisk-Users] Asterisk 1.0.2 - Unable to allocate channel
structure

Hi,
This morning I had some failed calls. On the console (and in the log)
I saw the error "Unable to allocate channel structure". Before I restarted
the process, I checked it's memory usage in ps and glanced at my free
memory in top. Asterisk was using a normal ammount of memory, about
40M. I don't think this was a system limit. This was running Asterisk
v1.0.2. Below is an excerpt of my messages log as well as the output
of ps and top, if it helps.
Has anyone seen this sort of error before? Any ideas what could be
causing it? The changelog for 1.0.3 doesn't list anything related
to memory or resource allocation.. Anyone know if there was any
work done to ast_channel_alloc() or related functions?
Thanks.
