Cognos起服务时出问题，关于Tomcat的，求助【结贴】

一开始重启服务，说是磁盘空间不够，我已经修改过，保证磁盘1G以上空间，现在重启又出现这个问题：
[Start Service]
1. [ ERROR ] An error has occurred within Tomcat. Please check the log file 'D:/cognos/c8/logs/tomcat.log'.
2. [ ERROR ] CFG-ERR-0106 Cognos Configuration did not receive a response from the Cognos 8 service in the time allotted.
Check that Cognos 8 service is available and properly configured.

求助关于tomcat的问题我该怎么去看。另外，这台机器上还装有其他Bi工具，不知道这之间有没有什么冲突？
求助各位高手了收起
