BUG() at tempesta_db/core/main.c:108 #136

Closed keshonok closed 9 years ago

keshonok commented 9 years ago

Test environment:

Tempesta starts fine. Then, the Firefox client is started in the same VM in order to issue a request. It is started with the following command: ssh root@192.168.10.230 -Y firefox, where 192.168.10.230 is the IP address on the Centos 7 VM with Tempesta. Tempesta crashes before the Firefox window can be seen.
