I don't know where is issue but from my thinking issue is on writing the command on replicated server.

Issue is not occurred continuously but sometime and when the issue is occurred then active time is 100% of the disk, check through resource monitor. so please let me know what to do for resolving this issue.

My distribution database is on subscriber .I have already  change the disk for distribution db and replication db and I havent restart the sql server so in resource monitor it show on the same drive but it change the drive the system catalog.

Thanks in advance
