check sp_configure "number of open objects" configuration parameter
and increase its value if its set to low.This error occurs when sybase fails to build an execution plan for a stored procedure or an ad-hoc query because a referenced object was not found. You can also refer to Sybase trouble shooting guide for error no. 225 write up
If increasing the parameter doesnt solve your problem , u may need to contact to Sybase Technical Support
I didnt see any error message in the errorlog regarding no. of open objects.
Infact I have tried option of increasing this config parameter but it doesnt help.
Secondly I dont see any error message which has been solved by CR 300706.
