thanks

This replica is on virtual machine (ganeti). We had problems with replication 
to vm, but after force-sync all was fine. On physical servers all works fine.
the messages indicate there could be  many concurrent operations, because 
individual ops are not fast enough, could your VM have less/slower resources 
than the physical machines ?
VMs have less rsources and slower than physical machines.
VM: 4 cpu, hd via drbd on sas drives,

physical: more cores, faster (ssd) drives

Hi,

there seem to be different issues,
- I don't know what the ipactl status is looking for when it generates the 
error message about no matching master,
but I don't think it is related to the retro changelog.

- the retro changelog errors for adding and deleting
-- the add failures are about aborted transactions because a page cannot be 
accessed, this maybe caused by concurrent mods on different backends, which 
want to update teh shared retro cl database.
the changenumber reprted seems to be increasing, one error is about 
changenumber 44975, the next about 45577, so it looks like changes into the 
changelog are written and teh changenumber increases
-- i'm not sure about the delete errors, but normally trimming would go on 
after such an error message, the changenumber attempted to delete are 
increasing.
Could you verify which changes are in the changelog, and if these are changing:
ldapsearch -b "cn=changelog" dn
