Hello,
how do you set newbody.s and newbody.len?

Not yet, because it is under developing, i could paste it here right away.
{ . . . body.s = get_body(msg); if (body.s == 0) { LM_ERR("failed to get the message body\n"); return -1; } body.len = msg->len - (int) (body.s - msg->buf); // body.len = strlen(body.s); if (body.len == 0) { LM_DBG("message body has zero length\n"); return -1; } l = del_lump(msg, body.s - msg->buf, body.len, 0); if (!l) { LM_ERR("del_lump failed\n"); return -1; }
if (!insert_new_lump_after(l, newbody.s, newbody.len, 0)) { LM_ERR("insert_new_lump_after failed\n"); return -1; }} I asked related issue in this regards in Kamailio developer forum, before. let me paste it at below. The means of other_process function is above code. In during developing new module in Kamailio, I encountered with strange behaviour. I used htable module instead of linked list for save some temporary data during call process.dependencies module to save some information. the skeleton of my code is like thus:
if (SIP_REQUEST &METHOD_INVITE) { insert_data_htable("some data"); other_process(msg); }else if(SIP_REPLY){ get_data_htable("some data"); other_process(msg); } In other_process function i have some changes in msg's body with message lump. But after i make first call in kamailio. The kamailio was crashed.What is it's problem? In additional if i comment either insert/get_data_htable function or othet_process function, i dont have this issue. With best regards.

Hello,
likely you didn't allocate the pointer inserted in data lump list. Is the code using data lumps available to look at on git?
Cheers, Daniel

Hello, What does this CRITICAL error mean? Jun 11 05:48:13 debian8 /usr/local/sbin/kamailio[8468]: {1 1 INVITE Njg0MzNhMzJhOTY3MzQ3NmNlNWY0ODkzMTJmNTM1ZTk.} CRITICAL: <core> [core/mem/q_malloc.c:486]: qm_free(): BUG: bad pointer 0xa3c188 (out of memory block!) called from core: core/data_lump.c: free_lump(466) - aborting
I got it when i make new call during debugging new module in Kamailio? In module we have to change some message's body with data_lump. I asked relaed issue (strange behaviour while developing new module) in Kamailio developer forum sr-dev@lists.kamailio.org With Best Regards.
