Resource Limits

RLIMIT_SIGPENDING (2.6.8)

• Limit on number of real-time signals that can be queued with sigqueue(2).
  
  
• In kernels < 2.6.8, /proc/sys/kernel/rtsig-max specified a system-wide limit on number of queued signals.
  
  
• Since 2.6.8, RLIMIT_SIGPENDING defines per-real-user-ID limit on the number of queued signals.
  
  
• Enforcing limit prevents exhaustion of kernel resources.
  
  
• Linux specific.
