[TYPO3-english] Cache going wild?

after a server-migration I experience some problems with the cache: I have several extensions
running on that site, which are working great so far and did before. After a server-migration I
experience problems with the detail-views of some extensions. Since these are the views using the
chash, I think there is something going wrong with the cache.
On the old server I had just a basic cronjob for the crawler-ext which I use together with
indexed_search. Now I added some cronjobs with own configurations for the crawler for every
extension because of better performance. Could that be related to my problem? I tested all the
cronjobs and configurations and they are working great. For example: I use a calendar-extension and
the crawler has a config for the detail-view and is correctly getting all the ID's of the events and
also correctly working them through and puts them into the index-tables. If I use the search it
works fine and I get the detail views correctly. But after some time (I am not sure which interval)
It shows like this: If the detail-view of the extension can't find an event in the corresponding
table, it gives back a failure-message formatted in HTML instead of the details of this event. After
an event is edited in the backend or people call the detail-view several times (sometimes it is ok
for days), it starts to show that error.
The conclusion of this? I think the cache stores wrong contents and gives them back because to a
given chash it stored the failure-message instead of the detailview. If I reset the cache manually
through the backend everything works fine, but starts again after some time. First I thought I did
something wrong in the crawler config, but the crawler-cronjob runs every night and the detail-view
does not break for every event on the next day after clearing the cache. Sometimes it is working for
days for a particualer event...
