Hello, Artur. How many concurrent requests did you have and are you running Tika Server on Windows? And what kind of files did you use?
You may have hit number of open files limit due to lot of reasons starting from known Windows issue (JVM process holds file descriptors for mmaped files until process killed) through just too low nofile limit to some Tika bug with handling for example stdin/stdout for forked processes. Could you provide jvm thread dump and lsof output (or Windows analog)? -- Best regards, Konstantin Gribov.
