I writes a module and compiles it fine.When ser receive invite request, this module will

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.
