java.lang.OutOfMemoryError: Failed to fork OS thread

hello guys, how are you ?

my platform

win server 2003

tomcat 5517

jdk IBM SR2 1.5

I'm having a problem I think since we migrated to IBM jdk 1.5.

Jasper Reports and just Jasper reports is thorwing this exception randomly once a week and makes all the tomcat server go down.

java.lang.OutOfMemoryError: Failed to fork OS thread

at java.lang.Thread.startImpl(Native Method)

at java.lang.Thread.start(Thread.java:963)

at net.sf.jasperreports.engine.fill.JRThreadSubreportRunner.start(JRThreadSubreportRunner.java:64)

at net.sf.jasperreports.engine.fill.JRFillSubreport.prepare(JRFillSubreport.java:546)

I saw the same error when creating images for the report, but the error was in the same place, java.lang.Thread.startImpl(Native Method)

any clue ? I cant find anything not even in google about this.

thanks

Rodrigo
