And you were right... Even though I thought the two servers were identical and identical installs, clearly they are not: Working server: collectl V3.6.7-1 (zlib:2.02,HiRes:1.9721) Broken server: collectl V3.6.7-1 I'll try the latest release on that server and let you know if this has the same problems (i.e. crashes without HiRes). In the long run, I suspect installing HiRes (and zlib) might be our preferred option.
