Subject Re: How to get heap dump of Tomcat running as windows service.
Date Fri, 14 Sep 2012 05:14:03 GMT
Hi,

Tried below option.
* jmap -J-Xmx512M -dump:format=b,file=heap.bin <pid>*

This too gives the same problem *"<pid>: Not enough storage is available to
process this command"*
**
**Thanks & Regards,
Aditi
