Interval_Max extending past runtime of jHiccup Jar file #49

Open mattvlr opened 2 months ago

mattvlr commented 2 months ago

Hello all,

I've been using jHiccup on close to a 5 min interval to listen for pausing on a bare-metal linux machine.

java -jar jHiccup.jar -t 295000

Normally the pausing stays within a pretty small timeframe, but on one of the files we had a pause of 5841155.523. Accounting for it being in milliseconds this is still 5,841.15 seconds which is way over my 5 min interval the profiler runs for.

I was wondering if we might know what occurred to cause this?

Attached is the .hlog file in question along with an example of a normal run for my process. suspect_file.csv normal_run.csv
