I'm running a Linux red Hat 9.0 with all updates, I have 512 MB ram, ser 0.8.12 . I writes a module and compiles it fine.When ser receive invite request, this module will be executed. Then I gets the following error message.

I change the value of PKG_MEM_POOL_SIZE by 10240*1024 in config.h and recompile. But I still has the same memory error message.How can get memory statistics when I send kill -SIGUSR1?

This looks like a memory leak in your module (or in SER?) unfortunately.
To get memory dumps printed, recompile SER with memory logging (i.e., replace -DF_MALLOC with -DDBG_QM_MALLOC in Makefile.defs) and set configuration option 'memlog' low (e.g., 'memlog=1'). On restart, SER will dump all unallocated fragments. It will be quite a lot -- each process will have many of them, but eventually we should be able to figure out some fragments which will be reocurring too frequently.
