Server Hangs

Hi ,

I have been assigned to do a research on the following statement which is coming continuously in our server log.Due to this sometimes our server hangs.But i am not able to find out the exact location from where the message is getting generated…i.e-the service which writes those messages in the server log.Can anyone please tell me how to find out the place from where te message is getting generated/whether there’s any webMethods internal services(wmRoot) which is causing the problem.

i think you have set the logging level to Info.

this will not harm your server i guess.If you want you can change your logging level to debug.

Thanks,
