Re: [SR-Users] DMQ Module Crash

Hello, I'm trying to replicate a hash table to another 2 nodes by using DMQ Module. That's the related configuration: loadmodule  "tm.so" loadmodule  "tmx.so" loadmodule  "dialog.so" loadmodule  "dmq.so" loadmodule  "htable.so" modparam("dmq", "server_address", "sip:MY_INTERNAL_IP_ADDR:5062") modparam("dmq", "notification_address", "sip:dmq.domain.local:5062") modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 4) modparam("dmq", "ping_interval", 90) modparam("htable", "enable_dmq", 1) modparam("htable", "dmq_init_sync", 1) modparam("htable", "htable", "test=>size=10;initval=0;dmqreplicate=1;")   if(is_method("KDMQ")) {     dmq_handle_message();     exit;   } After starting Kamailio - everything seems to be working fine, Kamailio is able to discover other nodes and replications is working fine, until after a few minutes I'm getting such errors in the Kamailio Log file: May  8 17:14:26 kamailio kamailio[28064]: CRITICAL: <core> [core/mem/q_malloc.c:521]: qm_free(): BUG: freeing already freed pointer (0x7f0ac62493e0), called from dialog: dlg_var.c: free_local_varlist(145), first free dialog: dlg_var.c: set_dlg_variable_unsafe(205) - ignoring Then, if I'm getting any SIP messages from any Device - Kamailio is crashing with the following info in the log file: May  8 16:03:19 kamailio kam[10963]: CRITICAL: {REGISTER (1) | Seq=45534 | Source IP=192.168.1.5 (tcp) | Call ID=Kyb-KJjf.U9ttdOwQNYu6mUWCKb2bvk7} <core> [core/mem/q_malloc.c:150]: qm_debug_check_frag(): BUG: qm: prev. fragm. tail overwritten(0, 0)[0x7f62cc746a10:0x7f62cc746a48]!  Memory allocator was called from dialog: dlg_var.c:147.

I've tried with 2 versions of Kamailio (5.2.6 and 5.3.4), both of them having the same issue.
