Hi,
We have some 3rd party library that writes one stack trace to STDERR which ends up as multiple rows in the log file:
2013-04-14 18:20:44,268 ERROR [] [STDERR] org.apache.wicket.WicketRuntimeException: Can't instantiate page using constructor 'public com.ongame.ip.promoweb.markup.pages.PromoWeb(org.apache.wicket.request.mapper.parameter.PageParameters)' and argument 'operatorID=[xxx], token=[xxx], lang=[sv], clientCode=[xxx]'. Might be it doesn't exist, may be it is not visible (public).

Each row in the stack trace gives a separate event in the Splunk index. Is there a way to concatenate this to one event?
We use log4j as logging framework. We have Splunk 4.3.2
Thanks
Try configuring your event boundarys :

Thanks,
however the regexp can be really complicated since we have to consider several threads writing to the log file concurrently (both stderr and normal logging). It can be hard to determine to which event a line belong to.
For now we'll redirect stderr to separate log file and exclude it from Splunk.
