Hi, I am seeing intermittent segfault's in ovs-vswitchd. We have like 20 compute nodes and noticed the crash in 4 or 5 nodes. Seems to me the crash is seen when the system is idle for a long time (as I noticed over the weekend)
We are using master of ovs (with the latest commit id 92043ab8ffd4) Below is the dmesg and the backtrace of the core file -------- [297752.801094] revalidator239[2308]: segfault at 0 ip 00007f2a8d966da3 sp 00007f2a28ff6c58 error 4 in ovs-vswitchd[7f2a8d8ef000+1ea000] ------------ [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1".
