You don't say which version of Java you're using, or which VM type. If the problem seems to be with Java and a type of VM, then a patch or config option for Tomcat is unlikely to make much difference. 1. Fix the Java problem 2. Check the VM is properly configured to provide the amount of memory you're trying to assign to Tomcat + whatever the OS needs. p > Thanks > Dominic > > Dominic Clarke > IT Advisor > Social Services IT > Caerphilly County Borough Council > 43 William Street > Gilfach > Bargoed > CF81 8ND > > Tel: 01443 873578 (Direct) > E-mail: clar...@caerphilly.gov.uk > > Social Services IT > tel 01443 87 3575 > fax 01443 87 3572 > > > > > > > > -------------------------------------------------------------------------------------------------------------------- > 'This email and any files transmitted with it are confidential and intended > solely for the use of the individual or > entity to whom they are addressed.
