Hello, A setup of Asterisk 12 with IMAP-uw 2007e works ok with the default value of "maxmsg=100" on voicemail.conf
However, if I increase that value to a higher limit (maxmsg=400, for example), Asterisk crashes when reaching a voicemail count of about 250 to 280 messages. I have reproduced this issue with different asterisk versions, see the full Asterisk backtrace and developer comments on https://issues.asterisk.org/jira/browse/ASTERISK-23759 I saw a similar problem on this email thread: https://mailman13.u.washington.edu/mailman/htdig/imap-uw/2007-October/001707.html Looks like the issue is on the double call to mail_open, but the Asterisk developers say the first calling of mail_open gives back an invalid handle to a MAILSTREAM. Maybe this is due to the number of messages beign too large? So far on all the tests the crash happens when the mailbox has more than ~250 messages. The fuction where mail_open is called twice is the following: ######## static int init_mailstream(struct vm_state *vms, int box) { MAILSTREAM *stream = NIL; long debug; char tmp[256]; if (!vms) { ast_log(LOG_ERROR, "vm_state is NULL!\n"); return -1; } ast_debug(3, "vm_state user is:%s\n", vms->imapuser); if (vms->mailstream == NIL || !vms->mailstream) { ast_debug(1, "mailstream not set.\n"); } else { stream = vms->mailstream; } /* debug = T; user wants protocol telemetry? */ debug = NIL; /* NO protocol telemetry? */ if (delimiter == '\0') { /* did not probe the server yet */ char *cp; #ifdef USE_SYSTEM_IMAP #include <imap/linkage.c> #elif defined(USE_SYSTEM_CCLIENT) #include <c-client/linkage.c> #else #include "linkage.c" #endif /* Connect to INBOX first to get folders delimiter */ imap_mailbox_name(tmp, sizeof(tmp), vms, 0, 1); ast_mutex_lock(&vms->lock); stream = mail_open (stream, tmp, debug ? OP_DEBUG : NIL); ast_mutex_unlock(&vms->lock); if (stream == NIL) { ast_log(LOG_ERROR, "Can't connect to imap server %s\n", tmp); return -1; } get_mailbox_delimiter(vms, stream); /* update delimiter in imapfolder */ for (cp = vms->imapfolder; *cp; cp++) if (*cp == '/') *cp = delimiter; } /* Now connect to the target folder */ imap_mailbox_name(tmp, sizeof(tmp), vms, box, 1); ast_debug(3, "Before mail_open, server: %s, box:%d\n", tmp, box); ast_mutex_lock(&vms->lock); vms->mailstream = mail_open (stream, tmp, debug ? OP_DEBUG : NIL); ast_mutex_unlock(&vms->lock); if (vms->mailstream == NIL) { return -1; } else { return 0; } } ###################### Any help would be appreciated, Thank you and best regards, Alejandro
