[Serusers] Memory error

[Mook]

Thanks, Jiri.

When I do these changes, got the following message.
 0(6096) ERROR: load_module: could not open module </usr/local/lib/ser/modules/mysql.so>: /usr/local/lib/ser/modules/mysql.so: undefined symbol: fm_malloc
 0(6096) parse error (31,13-49): failed to load module
ERROR: bad config file (1 errors)

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.
