Solve ssh logon error-bash fork retry Resource temporarily unavailable

An error is reported when a non-root user logs on to SSH. bash fork retry Resource temporarily unavailable.

This problem may be caused by/etc/security/limits. the nproc in the d/90-nproc.conf file has reached the upper limit, or the above configuration file has been released only for specific users, while other users still have restrictions.

The 90-nproc.conf here may be a machine.

The solution is to modify the nproc ceiling or the corresponding user account, and then restart the system to take effect.

Note: This file is only available after CentOS 6 and is not available in CentOS 5.10.

Perform the following steps:

1. cp-a/etc/security/limits. d/90-nproc.conf/etc/security/limits. d/90-nproc.conf.bak

Note: This operation is a backup file, which can be used for restoration to avoid Operation errors.

2. vim/etc/security/limits. d/90-nproc.conf

# Default limit for number of user's processes to prevent

# Accidental fork bombs.

# See rhbz #432903 for reasoning.

* Soft nproc 1024

Here, change 1024 to a greater value and set it as needed. For example, set it to 1500.

# Default limit for number of user's processes to prevent

# Accidental fork bombs.

# See rhbz #432903 for reasoning.

* Soft nproc 1500

If there is a limit on a specific user, modify the corresponding row content. For example:

# Default limit for number of user's processes to prevent

# Accidental fork bombs.

# See rhbz #432903 for reasoning.

Mayun soft nproc 1024

* Soft nproc 1500

To:

# Default limit for number of user's processes to prevent

# Accidental fork bombs.

# See rhbz #432903 for reasoning.

Mayun soft nproc 2000

* Soft nproc 1500

3. init 6

Note: restart the system

In addition, if this does not work, you can kill some processes of this user. If so, a process of this user has a loop and has been occupying some resources.
