Warning-Tension /Compression did not converge

I have completed a "Run Analysis" on a Staad model having the following support condition shown attachd. The Staad output gave the following:  **WARNING-Tension/Compression did not converge after 25 iterations.

What actions do I need to take in preparing the mode (Staad Editor) which would  prevent such a warning? When would it be safe to disregard such a warning. The loadings at which warning appears are primary load cases as shown attached.
