I had many issues with libevent. Switched the beta release of v2.x which helped some, and now there are later versions of libevent. However, bee communicating with Luca recently and he mentioned v3.4.x is no longer using libevent. I am still experiencing higher than expected CPU Util when performing 15 reverse lookups / sec, however, there are no longer any race conditions nor crashes relating to DNS stuff*
Gary *I ran 3.4.x code for several weeks with no issues. 3.3.x code would've had issues within 10 mins, or at most a 12 hours. ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Michael Scheidell Sent: Monday, December 21, 2009 2:24 PM To: [email protected] Subject: [Ntop] tracking down freebsd evdns assert failed issue? Freebsd, 6.4, i386, ntop 3.3.10. it (sorta) dies every now and then. I opened a console on the tty that started it, and when it (sorta) dies, I got this: Assertion failed: (req_waiting_head), function evdns_requests_pump_waiting_queue, file evdns.c, line 621. does this mean that the req_waiting_head queue doesn't exist? isn't big enough? any clue? this appears to be a libevent library call, and not an ntop issue? from libevent/work/evdns.c line 621: static void evdns_requests_pump_waiting_queue(void) { while (global_requests_inflight < global_max_requests_inflight && global_requests_waiting) { struct request *req; /* move a request from the waiting queue to the inflight queue */ assert(req_waiting_head); -- Michael Scheidell, CTO Phone: 561-999-5000, x 1259 > | SECNAP Network Security Corporation * Certified SNORT Integrator * 2008-9 Hot Company Award Winner, World Executive Alliance * Five-Star Partner Program 2009, VARBusiness * Best Anti-Spam Product 2008, Network Products Guide * King of Spam Filters, SC Magazine 2008 ________________________________ This email has been scanned and certified safe by SpammerTrap(r).
