adam brin updated WW-4536:
--------------------------
Description:
We've recently been having issues with our app crashing and trying to track
down the root causes. One of the things we've seen is that over the course of
1 day, 50% of our memory (almost 620 MB of 1.2 GB) is allocated to
"com.opensymphony.xwork.validator.AnnotationActionValidatorManager" according
to the heap dump. We also see millions of entries in two SynchronizedMap's:
* validatorCache (1,635,019 entries)
* validatorFileCache (87,321 entries)
Looking through the entries in the validator cache, we se entries for every
unique page browsed within the app. Note: we're using staticParam mapping and
NamedVariable PatternMatching in action names e.g. {{"$\{id\}/$\{slug\}"}} so
effectively every url is unique.
Looking at the source code, should these maps perhaps be "WeakHashMaps" or
WeakReferences so that they're disposed of?
(source code to the app is here: https://bitbucket.org/tdar/tdar.src/src )
