2491 | |||
2492 | max_user_instances | ||
2493 | ------------------ | ||
2494 | |||
2495 | This is the maximum number of epoll file descriptors that a single user can | ||
2496 | have open at a given time. The default value is 128, and should be enough | ||
2497 | for normal users. | ||
2498 | |||
2499 | max_user_watches | ||
2500 | ---------------- | ||
2501 | |||
2502 | Every epoll file descriptor can store a number of files to be monitored | ||
2503 | for event readiness. Each one of these monitored files constitutes a "watch". | ||
2504 | This configuration option sets the maximum number of "watches" that are | ||
2505 | allowed for each user. | ||
2506 | Each "watch" costs roughly 90 bytes on a 32bit kernel, and roughly 160 bytes | ||
2507 | on a 64bit one. | ||
2508 | The current default value for max_user_watches is the 1/32 of the available | ||
2509 | low memory, divided for the "watch" cost in bytes. | ||
