   I´ve also detected several AprMemCache errors; however, seems not directly 
related to craches since times does not correlate.:

   I´m running stock memcached 1.5.6 (ubuntu 18.04) under  Apache/2.4.29 in an 
exclusive instance for pagespeed. The other memcached instance runs smoothly 
with no issues.
   
   As I´m using mpm_prefork, I defined 2 threads per type to see if the issue 
comes from an overload but had no effect
    ModPagespeedNumRewriteThreads 2
    ModPagespeedNumExpensiveRewriteThreads 2
   
   BTW, a non related question. Is it possible to have the console show more 
than 24hrs of data?
   
   This is my pagespeed config
