zz1 lines in logfile and run taking a very long time

Hello,

I am running a PCA analysis with shrinkmode: YES and lsqproject: YES on 587,959 SNPs and 2175 individuals. I am using 11 threads. I have run very similar analyses before and they hadn't taken that long (24 hours and counting). In the logfile, I am seeing these lines (the eigensoft version I am using is 7.2.1):

Do you know if this means there might be something wrong with the run? Thanks a lot in advance!

Start by reproducing the PCA run with shrinkmode: YES and lsqproject: YES on comparable data, then inspect the logfile around the zzzdebug, zz1, and zzcpr output. Determine whether the run completes and whether those diagnostics indicate a failure or an unexpectedly slow path; document the observed outcome.
