There is a facility for debugging malloc on AIX. I enabled the malloc debugging on cf-serverd (non-threaded) on the policy host and I got some output. I am having a difficult time making sense out of it. Here is a excerpt from the output (the top hitters): HashControls SetNewScope NewScope malloc ################################ 278376 bytes leaked in 14 Blocks ################################ method_getentry open_attr_file_14_2 common_open malloc ################################ 262144 bytes leaked in 4 Blocks ################################ HashVariables SetNewScope NewScope malloc ################################ 198840 bytes leaked in 10 Blocks ################################ ExpandList ExpandPrivateRval strdup_5_3 malloc ################################ 165433 bytes leaked in 7901 Blocks ################################ AppendRlist CopyRvalItem strdup_5_3 malloc ################################ 154245 bytes leaked in 6428 Blocks ################################ NewAssoc CopyRvalItem AppendRlist malloc ExpandPrivateRval ExpandList AppendRlist malloc ################################ 126304 bytes leaked in 7894 Blocks ################################ main GenericInitialize NewScope malloc ################################ 119304 bytes leaked in 6 Blocks ################################ init_map_rules add_rule irs_lcl_ho malloc ################################ 64080 bytes leaked in 4874 Blocks ################################ AddVariableHash NewAssoc strdup_5_3 malloc ################################ 61470 bytes leaked in 2073 Blocks ################################ GenericInitialize SetNewScope NewScope malloc ################################ 39768 bytes leaked in 2 Blocks ################################ yylex yy_create_buffer yyalloc malloc ################################ 32868 bytes leaked in 4 Blocks ################################ NewScalar AddVariableHash NewAssoc malloc It is a little misleading as it is a dump of what currently is in memory that has not been freed. Most of it could be normal runtime operation at that moment in time. It does somewhat validate some of my suspicions that it is scope related as the environment for a connecting client may not have been fully freed. I poked around in the code, and it seems that it should be freeing the memory, which leads me back to nowhere. Hopefully someone with more CFengine-fu can interpret this better. _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
