Temporary cache files not properly cleaned

#36184

Hi,

We have a problem on our server with temporary cache files generated by PD4ML(pdtmp*.dat files). PD4ML keeps generating these files and consuming disk space without never clean them (see capture).

Could you please help with this ?

Best regards

Hi! The described behaviour depends on -Dpd4ml.cache.images.in.tmp.dir=true JVM setting and not-graceful shutdowns of the application, as the .dat files are created with tempFile.deleteOnExit(); property.

We’d recommend to update to PD4ML v4.0.16 (available as a snapshot build; it is going to be released in few days) with better cache control and change the JVM property to -Dpd4ml.cache.images.in.tmp.dir=false

Thanks a lot for your answer. We also tried to disable PD4ML cache management by setting this property as FALSE, but it doesn’t seems to have the expected effect : setParam(Constants.PD4ML_CACHE_ENABLE, “false”);

Could you please confirm that it should disable cache management on resources ?

Best regards

That depends on the version. There was a regression, when some properties were not correctly propagated to destination modules (i.e. cache).

Which PD4ML version do you currently use?

#36373

We are currently using the last release (v4.0.15fx2). Could you please provide us some visibility on the next release date ? Best regards

#36392

v4.0.16, which fixes this issue, is scheduled for release on Monday, May 22, 2023.
