I have the opposite, the problmeatic VM has 48 GB RAM assigned and most of that is used by caches and buzffers already.

I guess the more "read" calls are because I have unofficial sigs in use, but I wonder if the higher number of "usecs/call" is of any interest. I would have assumed that all sigs are already cached in the VM, making reading those inexpensive. Additionally, I don't see any reasonable I/O in the VM or host. % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 96.57 0.641536 4 142989 read 3.32 0.022027 6 3919 mmap 0.04 0.000293 0 3917 munmap 0.04 0.000239 4 66 fstat 0.03 0.000231 5 48 lseek 0.00 0.000000 0 17 write 0.00 0.000000 0 64 open 0.00 0.000000 0 76 close 0.00 0.000000 0 56 stat 0.00 0.000000 0 4 poll 0.00 0.000000 0 4 mprotect 0.00 0.000000 0 5 brk 0.00 0.000000 0 1 1 rt_sigreturn 0.00 0.000000 0 32 30 ioctl 0.00 0.000000 0 10 8 access 0.00 0.000000 0 2 select 0.00 0.000000 0 6 dup 0.00 0.000000 0 4 socket 0.00 0.000000 0 4 3 connect 0.00 0.000000 0 1 sendto 0.00 0.000000 0 3 recvfrom 0.00 0.000000 0 1 getsockopt 0.00 0.000000 0 1 uname 0.00 0.000000 0 5 fcntl 0.00 0.000000 0 6 getdents 0.00 0.000000 0 2 futex 0.00 0.000000 0 1 1 restart_syscall 0.00 0.000000 0 66 clock_gettime 0.00 0.000000 0 2 openat 0.00 0.000000 0 1 sendmmsg ------ ----------- ----------- --------- --------- ---------------- 100.00 0.664326 151313 43 total Mit freundlichen Grüßen, Thorsten Schöning -- Thorsten Schöning E-Mail: thorsten.schoen...@am-soft.de AM-SoFT IT-Systeme http://www.AM-SoFT.de/ Telefon...........05151- 9468- 55 Fax...............05151- 9468- 88 Mobil..............0178-8 9468- 04 AM-SoFT GmbH IT-Systeme, Brandenburger Str. 7c, 31789 Hameln AG Hannover HRB 207 694 - Geschäftsführer: Andreas Muchow _______________________________________________ clamav-users mailing list clamav-users@lists.clamav.net http://lists.clamav.net/cgi-bin/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
