There are error " READ_SWITCHSTATES_FAILED"

Question

hi, all.
     How can i do well?When i look over the function with SE37 the error will apper."The import of the current switch configuration from the database into an internal switch status buffer has failed."
"Error analysis
    The error when importing the current switch configuration into an
    internal switch status buffer can occur if the read enqueue lock, which
    is requested from the datatabase for consistent reading, is rejected due
     to a parallel change operation on this database.
    Furthermore, it could also be an internal problem preventing the request
     of the required enqueue lock.
    Specifically, the error situation in this case is described under 2 in
     the following:
    (1) A lock collision occurred when requesting the enqueue lock
     "E_ABAP_SWTSTATE".
        This enqueue lock is currently helb by user " " with enqueue owner
        ID " ".
    (2) The enqueue server rejects the enqueue request for the enqueue lock
        "E_ABAP_SWTSTATE" with the internal error code 8.
        Check any existing enqueue server entries in the developer trace."

Hi David,
Thanks for the insight. Yesterday, I changed ipc/... values using a sappfpar check. Today, it seems that I underestimate the ipc10 size and I redirect also other keys to 10. I double the ipc/shm_psize_10 parameter.
For information :
Dump : READ_SWITCHSTATES_FAILED
Job : SAP_PERIODIC_ORACLE_SNAPSHOT
related OSS Note : 1392449
On my system, the Note is not applicable as I run a NW04s system 7.0 SP18.

Tests done : it was the ipc/shm_psize_10 too small and some keys redirection too (30, 5* and 62).
Hope it helps someone else.
