[TYPO3-calendar] Cal Indexer Problem/ php limits

[Sebastian Reinhardt]

Hi,

we have some problems with the cal Indexer. But prob. a PHP limits 
probem. We have 269 Events, that all have recurencies on a specific 
weekday. so there are a lot of "indexes" to generate for the calindexer. 
  (with my Settings, the tx_cal_index will have 3432 entries after my 
"calindexing")

When i start the cal indexer i have to set the "index ending time" to 
20150115 (Jan 2015) when i us my start time "20140124". (so 3 Months) 
When i set a longer period, then the calindexer page wont show the infos 
after it is done, the result is a blank page.And the cal is broken in 
the frontend.

So what php limits do have to set, so the calindexer would work with 
longer periods in my case?

thx for helb/advice.

Sebastian
