Dateparse error out of the blue

[kottapar (R a V)]

@kottapar

filter {
if [logsource] =~ "esxs0[1,2].*" {
date {
match => [ "timestamp", "MMM dd HH:mm:ss" ]
locale => "en"
timezone => "UTC"
}

My bad. I made an elementary mistake
Here's my new filter. I didn't take into account "MMM d HH:mm:ss"

filter {
  if [logsource] =~ "esxs0[1,2].*" {
    date {
      match => [ "timestamp", "MMM dd HH:mm:ss", "MMM  d HH:mm:ss" ]
      locale => "en"
      timezone => "UTC"
    }
