RE: too many java processes ???
If you are having any problems with memory you can set the amount of memory it should consume by using these options with java command(on Linux). Add add these options read the tomat.sh file. -Xmsset initial Java heap size -Xmxset maximum Java heap size -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, April 06, 2001 2:06 PM To: [EMAIL PROTECTED] Subject: Re: too many java processes ???
