The server is running 0.8.10 with the following patches:
http://www.iptel.org/ser/issues/hash_fix.patch
http://iptel.org/~janakj/invroute.patch
http://www.iptel.org/ser/security/secalert-002-0_8_10.patch
http://www.mobile-ip.de/~andrei/ser/0.8.10/ser-0.8.10-bison-1.75.patch
Of these, the only one the indicates memory errors is the
invroute.patch. Has anyone seen this before?
No..
Could you stop the proxy and send us the memory status log dumped at the
end, or (if you don't want to stop it) kill -SIGUSR1 and again send the
mem. log.
What happens is ser runs out of local memory. ser uses shared memory
(you can specify the shared mem. size with -m) and "local" memory (per
process). The local memory can be alloc'ed/dealloc'ed much faster (it
does not require any locking). Usually ser runs out of shared mem., since
"local" mem. is used in general only for temporary storage.
ser will use maximum 1 Mb of "local" memory. So far we didn't need more.
As a quick fix you can try to increase the size. You will have to change
the value of PKG_MEM_POOL_SIZE in config.h and recompile.
