I am monitoring Windows EventLog.

When Zabbix Server receives the log of 255 or more Japanese characters(512 bytes or more ?), an error is outputted and data is not registered.

This problem occurs in zabbix1.8.8 and 1.8.9 and it does not coour in 1.8.7 and 1.8.6.

I guess that there is a problem in handling of the Japanese character after 255 character in 1.8.8 or later.

The following is a log when I test.

1) Zabbix v1.8.8
Japanese char 254 -> correct

[pg_log]
