In such cases, it is worth considering refreshing the caches in order to resolve the issue. A full reboot of the system is the surest way, as this will clear all of the caches involved - such as the operating system, database, application, and if done at the client level, there as well.
Naturally it is also possible to trouble-shoot the issue and look at root cause. Selective cache clearing will at least give the general area of the issue.
However, sometimes the cost/benefit will mean that the recycle of either the application or a more full approach of recycling the environment is worth considering.
