About 2 weeks ago SQL Anywhere server start crash about up to 5 times per day.
I'm try to catch error reasons but server do not write anything in logs to start investigation.
Server startup line looks like:
-n main_server -x tcpip(port=2638) -o d:\maindb.log -os 10M -oe d:\maindb_fatal.log -c 16g -ch 16g -gn 100 -xf d:\MainDB\server1state.txt d:\MainDB\main.db -sn main -xp "partner=(ENG=mirror_server;LINKS=tcpip(host=mirror_host;PORT=2638;TIMEOUT=1));auth=auth_string; arbiter=(ENG=arbiter;LINKS=tcpip(host=arbiter_host;PORT=2640;TIMEOUT=1));preferred=YES;mode=sync;autofailover=YES" -su su_pass
But then exception 0xc0000005 occurs nothing written in maindb.log or maindb_fatal.log. Primary server just stop working and mirror server become primary. And if I don't make any interventions after few hours mirror server stops too.
After translate transaction log last record always commit and previous records always linked to a different tables.
There is no environment changes makes on the Windows servers. And nothing valuable changes makes in database.
Did someone knows how to get more info about reasons of crash?
