wrobot shuts down a lot

hi,

recently my wrobot closes alot unexpectatly. There is no error message expect from the windows message "the program stopped working unexpectatly" (or something alike). the regular log looks pretty normal. this is kind of annoying because i really cant rely on the bot to run overnight or even some hours without shutting down. please let me know what kind of information i can provide (logs whatever) to shed light on the issue. thanks a lot.
