Server used to run fine. Over the last month, we've been experiencing problems with webaccess and the gwia. The strange thing is that sometimes we just get calls that the web access page is down. Other times, the gwia unloads as well. Also, when we check the instances of java (java -showall) only one instance is "loaded." We can reload java and start all services again, but when we do this, it seems the problem will occur again within two days. If we reboot the server, everything runs from anywhere from 3 days to two weeks. Here's the error:
