Local CQ instance Close automatically

Can you check your logs when you start the instance and also when it closes ?? If you see any errors please do post the same which would help us in finding the issue.

quickly, I can think of is it may be due to memory or disk space.

Whats your memory and disk space of your m/c ?

Hi Michael,

is that the end of the error log after your instance stopped unexpectedly? Usually if the instance is shutdown gracefully, you will get logs saying shutting down.

Does the instance stop at random times or the same time everyday? Are you monitoring the server to measure CPU/memory usage, as would be good to see what is happening when the instance stops.

Are you using windows or linux?

Regards,

Opkar 

I dont see any error or problems here... Do you mind attaching the complete log file !

Also what is your system configuration ?

Yup, it says Out of Memory

Please ensure you have sufficient main memory and disk space, Delete some stuff from you disk to get empty space and it will work fine.

You can also start your instance from command line by giving these values. refer [1] for the same
