Thanks for your quick reply!
MTU is 9000 on all interfaces regarding intercluster. The nexus switches also have a high mtu:9216 and the source cluster also has mtu 9000
cluster peer ping works every time:
drs1::*> cluster peer ping -destination-cluster nac1
Node: fas13a Destination Cluster: nac1
Destination Node IP Address Count TTL RTT(ms) Status
---------------- ---------------- ----- ---- ------- -------------------------
fas14a x.x.x.82 1 255 0.262 interface_reachable
fas14b x.x.x.84 1 255 0.26 interface_reachable
fas15a x.x.x.86 1 255 0.291 interface_reachable
fas15b x.x.x.88 1 255 0.247 interface_reachable

(i obfuscated the ip's)
Lowering the MTU to 1500 seems quite a waste to me 😉
Doesn't seem to be this issue or at least i'm not seeing what the KB article is describing
Interesting fact, it is almost exact on the quarter of an hour

the 00 / 15 /30 /45 match with the snapmirror schedules
hourly0 @:00
hourly1 @:15
hourly2 @:30
hourly3 @:45
But the snapmirrors seem to be oke
drs1::snapmirror*> show -fields last-transfer-error-codes,last-transfer-error,status,last-transfer-end-timestamp ,healthy,last-transfer-size
source-path destination-path status healthy last-transfer-error last-transfer-error-codes last-transfer-size last-transfer-end-timestamp
