[sr-dev] [tracker] Task opened: Possible memory leak when processing sht_reload

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. A new Flyspray task has been opened. Details are below. User who did this - i (takeshi) Attached to Project - sip-router Summary - Possible memory leak when processing sht_reload Task Type - Bug Report Category - Core Status - Unconfirmed Assigned To - Operating System - All Severity - Low Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - I am testing reload of htable using 'kamctl fifo sht_reload TABLE_NAME' This worked fine before and I could issue thousands of such commands without rest. But with latest commit ef66bf4ce961a7379bb21e848f70d03defb8864c, it fails after about 40 reloads (using the same config file and '-m 1024') with 500 ERROR Reloading data Setting debug=9 didn't clarify the reason so I attached to the "MI FIFO" process with gdb and verified that it goes out at this point in htable.c (inside function ht_mi_reload): nht.entries = (ht_entry_t*)shm_malloc(nht.htsize*sizeof(ht_entry_t)); if(nht.entries == NULL) { ht_db_close_con(); return init_mi_tree(500, MI_ERR_RELOAD, MI_ERR_RELOAD_LEN); } The problem is with shm_malloc() so it seems there is a memory leak. The configuration is just this: # ----- htable params ----- modparam("htable", "db_url", "mysql://kamailio:kamailioro@localhost/kamailio") modparam("htable", "htable", "domain=>size=20;dbtable=htable_domain;") And I am not processing any calls, I just do 'kamctl fifo sht_reload domain' in a loop. I even added a sleep of 5 minutes between reloads to see if memory eventually gets freed but it failed just the same: root@LAB002153:sip-router# for i in $(seq 1 50);do echo $i; kamctl fifo sht_reload domain; sleep 300; done 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 500 ERROR Reloading data 43 500 ERROR Reloading data 44 500 ERROR Reloading data I got the memory dump after shutting down kamailio. It is too big for pastebin, so I uploaded to a file sharing service: http://www.filedropper.com/kamailiolog But I don't know how to interpret this.
