Hi,
I've have installed SAP ERP 6.0 EHP6 on windows /sybase ASE 15.7.0.041 and system was running well from several days.
Tomorrow I've got this unexpected error in the ASE log file:

Sybase ASE has stopped working, SAP processes has changed their status in reconnected mode.
After 20-30 minutes of Sybase activity (sqlserver.exe process was running with high CPU consumption - see log file reported below), I've reboot the server (the only way to restart application) and now SAP System is online. ASE has made recovery with no problem.
Windows system is virtualized with VMware; no error was reported in the Event System of windows server.
No error was reported by VMware event log.
Do you have any idea what might have happened ?
Thanks
Maurizio Manera
