After migrating from 3.5 to 4.10.3, I'm seeing the following error with alarming regularity in the master's error log:
2/15/2016, 4:32:22 PM ERROR PDSimpleFont Can't determine the width of the space character using 250 as default I can't seem to glean much information about this one from the web. Has anyone else fought this error? In case this helps, here's some technical/miscellaneous info: - I'm running a master-slave set-up. - I rely on the ERH (tika/solr-cell/whatever) for extracting plaintext from .docs and .pdfs. I'm guessing that PDSimpleFont is a component of this, but I don't know the first thing about it. - I have the clients specifying 'autocommit=6s' in their requests, which I realize is a pretty aggressive commit interval, but so far that hasn't caused any problems I couldn't surmount. - There are north of 11 million docs in my index, which is 36 gigs thick. The storage volume is only 10% full. - When I migrated from 3.5 to 4.10.3, I correctly performed a reindex due to incompatibility between versions. - Both master and slave are running on AWS instances, C4.4XL's (16 cores, 30 gigs of RAM). So far, I have been unable to reproduce this error on my own: I can only observe it in the logs. I haven't been able to tie it to any specific document. Let me know if further information would be helpful.
