cognos导致服务器停止

[m.cognos.pogo.reportservice.ProcessManageer] warpmta-ProcessManager-ProcessMgrThread:External Report Server process BIBusTKServerMain cannot be started java.io.IOException: Cannot run program "/ibm/cognos/c10_64/bin/BIBusTKServerMain"(in directory "/ibm/cognos/c10_64/bin"): java.io.IOException:error=12,Cannot allocate memory

服务器重启，然后点击报表，过一会儿CPU则达到百分之一百多，导致服务器挂了。现不知道问题原因在哪里，望专家来解答收起
