Adding new Host hangs

[worksyn]

Hello,

i'm running zabbix-server 3.0, I have added ~25 hosts, however when i try to add one more, after entering hostname and group clicking on "Add" - it just hangs for ~1 minute and shows ERR_CONNECTION_RESET in browser. The same happens if i try to link template to Host.

Does Anybody face the same before?

UPDATE:

if i try to add host using API method host.add.json - then it works. any thoughts why it's not working from Web interface?

Any errors in Apache error log?

Any errors in Apache error log?

hi, no errors in apache logs.

ps. strange after adding host from API, it started to work from CP, however sometimes hangs again on linking template to host. I see request in apache access_log, however no errors in error_log or in zabbix_server.log, how to better troubleshoot it? strace apache processes or zabbix?

Does restarting the apache solves the problem ? Just trying to localize the issue. So basically your front-end adds new hosts directly to the SQL database and there is nothing to do with the Zabbix Server daemon.

Could you try:
1. to restart the Apache server?
2. try to perform the operation with another browser?
