Hi everybody,   I'm using Poolman1.4.1 with tomcat3.2.It can be run smoothly at first, but after few hrs the tomcat will be shutdown and "Dr Wattson" promopt up an error box say:"java.exe error, Invalid Access(0xc0000005)".Do anybody know what's happening ? Also the poolman sometimes display "Invalid handle/General error" on the console of tomcat3.2.......Can anybody tell me why this happen ? thx!
