Algorand Specifications
| Parameter Name | Default Value | Introduced in Version | Last Updated in Version |
|---|---|---|---|
ReservedFDs |
256 |
2 | 2 |
Description:
This configuration parameter specifies the number of reserved file descriptors
(FDs) that the node will allocate. These reserved FDs are set aside for operations
that require temporary file descriptors, such as DNS queries, SQLite database interactions,
and other short-lived network operations. The total number of file descriptors available
to the node, as specified by the node’s file descriptor limit (RLIMIT_NOFILE),
should always be greater than or equal to:
IncomingConnectionsLimit + RestConnectionsHardLimit + ReservedFDs.
This parameter is typically left at its default value and should not be changed unless necessary. If the node’s file descriptor limit is lower than the sum of the three components, it could cause issues with node functionality.
